Unnamed Irises

Everyone, especially HIPS people:
I'm wondering--what are the chances that the old-fashioned iris we run into
here and there once had a real name? Did many non-registered iris sneak out
of the nurseries, or did a large percentage of them simply become separated
from their names as the years went by?

irises and wishing the 100+ days would go away
